The actual size of the H7N9 Xiaoshan/Ningbo Wanf/Yu cluster in Zhejiang is far from clear. Yesterday media reports focused on 3 cases in the Xiaoshan region of Hangzhou. At that time there were four cases named Wang (with at least 2 in Xiaoshan) and two cases name Yu (both in Xiaoshan).

Initial reports last night suggested family members named Wang, who live near Donghu Lake in Xiaoshan. One case named Wang (71F) lived by "Riverside" which is likely Donghu Lake, while the Ningbo DoH noted that the family had moved from Ningbo to "East Lake", which is likely Donghu Lake.

The case in Ningbo (57M) is mild (as is 43F, the wife of fatal 49M), which is likely a contact of a confirmed case since mild cases are not tested for H7N9 unless they are contacts of confirmed cases.

Thus, the cluster described as 3 family members name Yu or Wang may actually represent SIX confirmed H7N9 cases.

Hi Dr. Niman-

So... what is your sense so far of the evolution of H7N9 in general and/or in the context of upcoming Chinese New Year?

Prior to this cluster, the largest confirmed cluster was 2 (and the most recent H7N9 sequences from northern China are from October).
